Mobile Terminal with New Type of Antenna Structure

1. A mobile terminal with a new type of antenna structure, wherein the antenna structure comprises: a metal rear cover; a first slot disposed on the metal rear cover, wherein a first end of the first slot connects with a lateral face or an end face of the metal rear cover; a second slot disposed on the metal rear cover, wherein the second slot is located on a first side of the first slot, and wherein a first end of the second slot connects with a second end of the first slot; a third slot disposed on the metal rear cover, wherein the third slot is located on a second side of the first slot, and wherein a first end of the third slot connects with the second end of the first slot, wherein the metal rear cover comprises: a rear cover located adjacent to a first side of the second slot and a first side of the third slot; a first antenna part located adjacent to the first side of the first slot and a second side of the second slot; and a second antenna part located adjacent to the second side of the first slot and a second side of the second slot, wherein both the first antenna part and the second antenna part are integrally connected to the rear cover; and an antenna feed point disposed on the first antenna part and/or the second antenna part, wherein the antenna feed point is connected to a transceiver of the mobile terminal using a feeder; and an antenna extension part connected to the first antenna part, wherein the first antenna part is connected to the antenna extension part using a spring plate or an elastic ejector pin.

2. The mobile terminal of claim 1 , wherein the antenna feed point is disposed on the first antenna part, and wherein a first end of the antenna extension part is connected to the first antenna part.

3. The mobile terminal of claim 2 , wherein the antenna extension part is connected to a conductor inside the mobile terminal.

4. The mobile terminal of claim 3 , wherein the first end of the first slot connects with a bottom of the metal rear cover.

5. The mobile terminal of claim 3 , wherein the first slot, the second slot, and the third slot form a T-shaped slot.

6. The mobile terminal of claim 3 , wherein the first antenna part comprises a connection point, wherein the first end of the antenna extension part is connected to the connection point, and wherein the antenna extension part comprises: a first extension part that extends in a direction of the rear cover; a second extension part that extends in a direction leaving the first slot from a tail end of the first extension part; a third extension part that extends in a direction opposite to the rear cover from a tail end of the second extension part; and a fourth extension part that extends in a direction approaching the first slot from a tail end of the third extension part.

7. The mobile terminal of claim 6 , further comprising: a first antenna path from the first antenna part via the connection point to the antenna extension part; and a second antenna path from a joint between the second antenna part and the rear cover to an opposite direction of the rear cover and a direction of the first slot, wherein a fundamental mode and a higher order mode of the first antenna path form a low-frequency resonance and a first high-frequency resonance respectively, wherein a space coupling exists between the second antenna path and the first antenna path, and wherein the second antenna path is excited to form a second high-frequency resonance.

8. The mobile terminal of claim 1 , wherein an area of the rear cover is greater than an area of the first antenna part and an area of the second antenna part.

9. A mobile terminal with a new type of antenna structure, wherein the antenna structure comprises: a metal rear cover; a first slot disposed on the metal rear cover, wherein a first end of the first slot connects with a lateral face or an end face of the metal rear cover; a second slot disposed on the metal rear cover wherein the second slot is located on a first side of the first slot, and wherein a first end of the second slot connects with a second end of the first slot; a third slot disposed on the metal rear cover, wherein the third slot is located on a second side of the first slot, and wherein a first end of the third slot connects with the second end of the first slot, wherein the metal rear cover comprises: a rear cover located adjacent to a first side of the second slot and a first side of the third slot; a first antenna part located adjacent to the first side of the first slot and a second side of the second slot, wherein the first antenna part comprises a connection point; and a second antenna part located adjacent to the second side of the first slot and a second side of the second slot, and wherein both the first antenna part and the second antenna part are integrally connected to the rear cover; an antenna feed point disposed on the first antenna part, wherein the antenna feed point is connected to a transceiver of the mobile terminal using a feeder; and an antenna extension part, wherein a first end of the antenna extension part is connected to the connection point, wherein the antenna extension part is connected to a conductor inside the mobile terminal, and wherein the antenna extension part comprises: a first extension part that extends in a direction of the rear cover; a second extension part that extends in a direction leaving the first slot from a tail end of the first extension part; a third extension part that extends in a direction opposite to the rear cover from a tail end of the second extension part; and a fourth extension part that extends in a direction approaching the first slot from a tail end of the third extension part.

10. The mobile terminal of claim 9 , wherein the first antenna part is connected to the antenna extension part using a spring plate or an elastic ejector pin.

11. The mobile terminal of claim 9 , wherein the first end of the first slot connects with a bottom of the metal rear cover.

12. The mobile terminal of claim 9 , wherein the first slot, the second slot, and the third slot form a T-shaped slot.

13. The mobile terminal of claim 9 , wherein an area of the rear cover is greater than an area of the first antenna part and an area of the second antenna part.
